Title: Migration-resistant amylaceous forming size compositions for fibrous glass
IPC: C08B31/00
Filed: 1962-02-22
Abstract: An aqueous dispersion for treating glass fibres comprises 1,5-9% of starch, 0,5-6% of a non-ionic lubricant, and 0,05-1,5% of a cationic lubricant, the starch consisting of 50-70% of amylose and 30-50% of amylopectin.  The starch may be the hybrid maize starch known as "Amylon".  The non-ionic lubricant is a natural or synthetic glyceride oil, which may be hydrogenated.  The cationic lubricant may be tetraethylene pentamine distearate.  0,025-2,5% of an emulsifier, e.g. polyethylene glycol or polyoxyethylene sorbitan mono-oleate, may also be present.  An example is given of the use of hybrid maize starch which has been cooked in aqueous suspension after the pH has been adjusted to 6,0\sB0,2 by the addition of hydrochloric acid. After coating the glass fibres are formed into strands or yarn, dried, and wound.

Convention date, May 29, 1935. [Class 17 (i)] Pulling-over.-In a pulling-over machine of the " inverted " type having devices, carried by the tack blocks, for pressing the upper against the sides of the last, the devices are arranged to project substantially beyond the tack blocks when the machine is at rest. As shown, a member 9 secured to the tack block 8 by a bolt 10 forms a guide for two slides 15, 16 which carry a yielding band 24 for pressing the upper. The slides are pressed forwardly independently by levers 26 pivoted on the member 9 and biassed by springs 30. When the block 8 is moved inwardly to tacking position the slides 15, 16 first engage the upper, and then yield until a projection on the slide 16 engages a cover plate 17, which is adjustable to determine the spacing of the tacks from the insole edge. Wiper plates 13 guided by the member 9 have their forward ends tilted upwardly by means of spring- pressed rolls 32 engaging their rear ends. Tack passages 23 are formed in the slide 16 and are adjusted by a screw 35, to alignment with the driver passages in the tack block 8. The two slides 15, 16 may be replaced by a single member if the tack block 8 is pivotally mounted on the tacker arm 5.

Abstract: 644,212. Regulation of pumps. PARSONS & CO., Ltd., C. A., and METCALFE, F. March 12, 1948, No. 7621. [Class 102(i)] [Also in Groups XI and XXVI] An emergency cut-off valve for the fuel supply to the spill type burners of a gas turbine combustion chamber comprises a body 2 having a duct 11 connected to the fuel supply line, a duct 10 connected to a return pipe to the fuel supply system, a duct 9 connected to the burners, a duct 8 connected to the spill return from the burners and a duct 12 connected to drain. A reciprocative plunger 3 with lands 4, 5, 6 and 7 is mounted in the bore of the body 2. In the position of the plunger shown, fuel from the pump passes through the ducts 11 and 9 to the burners and the spill passes from the burners through the ducts 8 and 10 to the pump inlet. When the plunger 3 is pushed to the left, the land 6 shuts off the supply to the burners through the duct 9, the duct 11 is connected to the duct 10 and the duct 8 connected to the drain 12. This allows the fuel pump to continue to operate and the spill pressure to be relieved. To maintain the plunger 3 in balance, equalizing passages 14 and 15 are provided. The plunger may be operated by hand, by solenoid, or by a servo piston from the emergency governor oil supply.

Abstract: 1,219,129. Bottle caps. POLYTOP CORP. 16 Feb., 1968 [16 Feb., 1967], No. 7748/68. Heading B8T. A cap for sealing bottles consists of a top 12 and a depending skirt 14 which has means, e.g. a screw-thread, to retain the cap on the bottle neck, a seal being formed with the neck by a circular resilient ring 18, a lip 28, and a deflecting cone 22. As the cap is screwed or pushed on the bottle, the cone 22 enters the neck, pressure of the neck on the cone causing inward twisting of the cone and the ring 18 to which it is attached. Further downward movement causes the lip 28 to engage with the top (34), Fig. 3 (not shown), of the neck, forming another seal. The cap is made of resilient material, e.g. polyethylene, and may include a dispensing spout. The cap may be secured by screw threads or by an interior rib on the skirt 14 snapping over a rib on the bottle neck.

Abstract: 462,933. Gas producers. KRUPP AKT.-GES., F. March 17, 1936, No. 7982. Convention date, March 23, 1935. [Class 55 (i)] In a gas producer in which the air supply, with or without steam, and the gas withdrawal are effected in the neighbourhood of the gasefication zone, the former is introduced through a central pipe 12 and the latter removed through outlets 3 in the periphery of the shaft, so as to produce a relatively shallow gasefication zone of truncated conical form with symmetrical flow of the gases therethrough. The direction of gasefication is reversible by interchanging the air supply and gas withdrawal. In a modification of the process, the gas supply and withdrawal are effected at the same level so as to produce a disc-shaped gasefication zone. In the alternative method of working, steam from a heat-exchanger 15, supplied with feedwater from an annular tank 16 in the upper part of the shaft and heated by the evolved gases from the pipe 12, is supplied to an external ring-shaped pipe 6 provided with spaced nozzles 7 terminating in front of nozzle-shaped vertical air inlets 5, the gases thoroughly mixing in an annular channel 4 within the wall of the producer before issuing into the fuel bed through horizontal spaced nozzles 3 arranged below the narrowest section of the shaft. The wall of the producer is thus cooled. If the latter is unnecessary such as with a wall composed of sillimanite, the channel 4 and inlets 5 may be dispensed with. Air may also be mixed with the steam in the heat-exchanger through a valved inlet 19. The single offtake pipe 12 may be replaced by a number of concentrically arranged pipes, these pipes being provided with perforated hoods 13 to prevent removal of fuel particles.. In the reversed method of working, the steam supply pipes 18, 6 are removed and replaced by draw-off pipes for the gaseous products connected to the vertical channels 5. In a modified form of the producer, the cooling channels 4, 5 in the shaft wall are replaced by an air- or water-cooled jacket, and the steam admission nozzles 7 terminate horizontally in front of the horizontal air inlets 3, the latter being also cooled by the jacket through which they pass. The upper part of the jacket is of spiral form to increase the cooling air velocity.
